The British Antarctic Survey determined that the crack has expanded by 50 miles since 2011.
"It is particularly hard to predict when it will occur," Adrian Luckman of Project MIDAS told USA TODAY about the eventual calving, which would create a Delaware-sized iceberg. "I am quite surprised as to how long it is holding on!"
"The rift (or crack) has continued to open, and the berg continues to drift outward at a very consistent rate," Luckman added.
However, he noted that the crack has not grown longer in recent weeks.
As EcoWatch mentioned previously, the loss of this portion of the ice shelf will not raise sea levels as it is already floating on the water. However, as these ice shelves disintegrate, the land-locked glaciers they hold back may begin sliding into the sea. If all of the ice the Larsen C ice shelf holds back slides into the ocean, it will raise sea levels globally by four inches.
According to Project MIDAS, "there is not enough information to know whether the expected calving event on Larsen C is an effect of climate change or not, although there is good scientific evidence that climate change has caused thinning of the ice shelf."
Temperatures at the Antarctic Peninsula, where the Larsen ice shelf is found, have risen by 2.5 degrees Celsius in the past 50 years.
Antarctica's ice shelves are indeed melting rapidly as ocean waters warm. Climate Nexus reported in October that three glaciers in West Antarctica have undergone "intense unbalanced melting," risking their stability and further acceleration of sea level rise.
Research published in Nature Communications found that the Smith, Pope and Kohler glaciers in the Amundsen Sea embayment collectively lost about 1,000 feet of ice from 2002 to 2009.

Singapore will become the first country in the world to place a ban on advertisements for carbonated drinks and juices with high sugar contents, its health ministry announced last week. The law is intended to curb sugar consumption since the country has some of the world's highest diabetes rates per capita, as Reuters reported.

First there was Fred Stone, the third-generation dairy farmer in Maine who discovered that the milk from his cows contained harmful chemicals. Then came Art Schaap, a second-generation dairy farmer in New Mexico, who had to dump 15,000 gallons of contaminated milk a day.
California Governor Gavin Newsom signed into law a bill that that bans the sale and manufacture of fur products in the state. The fur ban, which he signed into law on Saturday, prohibits Californians from selling or making clothing, shoes or handbags with fur starting in 2023, according to the AP.

During the three months of July, August and September, renewables generated an estimated total of 29.5 terawatt hours (TWh), compared with just 29.1TWh from fossil fuels, the analysis shows.
